Description

Needle pressing rod structure and embroidery machine [ Field of technology ] The utility model belongs to the technical field of embroidery equipment, and particularly relates to an embroidery machine. [ Background Art ] In the prior art, the needle bar is also provided with a top dead center above the bottom dead center, and the needle bar is matched with the middle beam on the needle bar frame above through the top dead center to stop at the highest position of the up-and-down movement of the needle bar driver and the presser foot driver, so that the bottom dead center can be combined with the needle bar driver. But can collide with the middle beam of the needle bar frame when the upper dead point is limited during working, and noise is generated. In order to avoid the noise, the applicant intends to cancel the upper dead point, the lower dead point is always combined with the needle bar driver when in operation, and the maximum working stroke of the needle bar driver ensures that the lower dead point cannot collide with the needle bar frame, so that the noise is reduced when in operation, but before the needle bar and the presser foot work, the needle bar is pressed down by adopting a needle bar pressing structure to combine the lower dead point with the needle bar driver, and the presser foot is matched with the presser foot driver. [ utility model ] Aiming at the defects in the prior art, the utility model aims to provide a needle pressing rod structure and an embroidery machine, and solves the problems that a needle rod is combined with a needle rod driver by pressing the needle rod down and a presser foot is matched with a presser foot driver. In order to solve the technical problems, the utility model adopts the following technical scheme: First, a needle pressing rod structure is provided, which comprises a needle rod, a driving shaft, a needle pressing rod motor and a pressing rod, wherein a needle rod driver is movably arranged on the driving shaft, a bottom dead center is fixed on the needle rod, the needle pressing rod motor drives the pressing rod to enable the pressing rod to press down the needle rod, so that the needle rod driver corresponds to the bottom dead center in height, and the needle rod driver is connected with the bottom dead center and drives the needle rod through the bottom dead center. Preferably, the pressure lever is rotatably mounted above the needle bar, and a pressing section for pressing the needle bar is arranged on the first side of the rotation fulcrum of the pressure lever. Preferably, an output shaft of the needle pressing rod motor is connected with a cam, the pressing rod is provided with a lifting section on the second side of the rotating fulcrum, and the cam is matched with the lifting section when the needle bar is pressed down and used for driving the lifting section to lift upwards. Preferably, an included angle is formed between the pressing section and the lifting section. Preferably, the connection part of the pressing section and the lifting section is provided with a protruding section extending downwards, and the protruding section is connected with the pivot shaft. Preferably, the compression bar is connected with an elastic reset piece for realizing the rising of the pressing section. Preferably, the elastic restoring member is a first torsion spring. Preferably, a second torsion spring is connected to the cam. Preferably, the needle pressing rod motor is mounted on a motor support, the motor support comprises a bottom plate and a vertical plate, the needle pressing rod motor is mounted on a first side of the vertical plate, the pressing rod is rotatably mounted on a second side of the vertical plate, and the cam is arranged on the second side of the vertical plate. In addition, the utility model also provides an embroidery machine which comprises the needle pressing rod structure. The needle pressing rod structure comprises a needle pressing rod motor and a pressing rod, wherein the pressing rod motor drives the pressing rod to enable the pressing rod to press down the needle rod, and therefore the needle rod driver corresponds to the lower dead point in position in height. Thus, before the needle bar and the presser foot work, the needle bar pressing structure works, after the needle bar is pressed down by the needle bar pressing structure, the needle bar driver is combined with the bottom dead center through the clutch structure, meanwhile, the bottom surface of the presser foot positioning block is abutted with the presser foot driving part, the needle bar pressing structure resets, and the needle bar and the presser foot are correspondingly driven by the follow-up needle bar driver and the conjugate cam presser foot driving device to work. These features and advantages of the present utility model will be disclosed in detail in the following detailed description and the accompanying drawings.
